SOLDERlNG-IRON.

SPECIFICATION forming part of Letters Patent No. 369,617, datedSeptember 6, 1887.

Application filed July 2,1887. Serial No. 213,247. (No modeLl T0 ctZZwhom it may concern.-

Be it known that l, CHRISTIAN G. SoiINEI- DER, a citizen of the UnitedStates, residing at Washington, in the District of Columbia, haveinvented a certain new and useful Improvement in Soldering-Irons, ofwhich the following is a full, clear, and exact description.

This invention relates to that class of solderingirons in which thecopper or bolt is heated by being applied to a gas-burner, the flamefrom which'enters the said copper or bolt, and then, passing out,envelops it.

The invention consists in a soldering-iron having a copper or boltprovided with an interlor cavity opening externally and forming agas-cham ber, whereby the copper or bolt may be applied to or haveapplied to it an ordlnary illuminating-gas burner with'a flame, theflame filling the said chamber and escap- 1ng outwardly therefrom andenveloping the copper to heat it.

The invention also consists in a spring-handle for automaticallyengaging the bolt, the bolt being swiveled to the said handle, andthereby adapted to be used in alignment with t or at right anglesthereto, for convenience in getting at the work in hand.

In the accompanying drawings, in the several figures of which like partsare similarly designated, Figure 1 is a perspective view of my solderingiron applied to an ordinary bracket illuniinatinggas burner. Fig. 2 isan elevation, with the bolt or copper in section. Fig. 3 is a similarview of another form of bolt, and also shows the bolt provided withaburner so that it may be connected by a tube to a gas burner, andthereby receive a constant flame or carry the heat-producing agent alongwith it. Fig. etis a side elevation, with the copper or bolt shown intwo positions, the tip of the copper being broken off and the end of thehandle also being removed to come within the sight of the drawing; andFig. 5 is an elevation of the bolt turned down at right angles with thehandle, part of the handle being also shown.

The bolt a may be of any ordinary construction so far as external shapeand material are concerned. I provide it with an external projection atthe base of the tinned portion,whioh projection is shown as a bead, b,in Figs. 1, 2,

4, and 5, and as a shoulder, Z), in Fig. 3, for a purpose hereinafterexplained. Either or both forms are comprehended in the term projection.I also provide the bolt with opposite openings or sockets, c, to receivethe ends of the handle d, and, furthermore. I provide it with transversegrooves e and intersecting longitudinal groovesf, which respectivelyengage the limbs of the handle when the bolt is turned at right anglesthereto or in alignment therewith.

The handle d is composed of metal bent in the form of a bow, and havingthe free ends of its limbs d d turned in toward each other to formgudgeons g, which enter the openings or sockets c, to engage and holdthe bolt. The limbs'of the handle d are forced toward each other by theelasticity of the metal, and this elasticity is sufficient to firmlygrip the bolt and hold it in either of the positions described.

The bolt is provided with a central cavity, h, which may be made withparallel sides, as indicated in Fig. 2, or which may be made spherical,or nearly so, as indicated in Fig. 3, and this chamber communicates withthe external atmosphere by means of openings 6, which are arranged justbeneath the projection, hereinbefore referred to.

Vhen the bolt is applied to a gas-burner, as indicated in Fig. 1, thegas having been lighted, the flame will issue from the holes 3, and,passing over and around the projection, will lick around the point ofthe bolt or copper and thus heat it. The projection will serve to arrestwhatever soot there may be, and thus keep the point of the copper orbolt clean. The requisite quantity of air is ad mitted into the bolt orcopper by the transverse intersecting channelsj and the openings k. Ihave found that the desirable blue flame in which there is practicallyno soot-that is to say, in which the combustion is practicallyperfect-is best obtained by employing a gaschamber substantially of theshape indicated in Fig. 3.

Long prior to this invention it was common to supply to a bolt means forburning illuminating gas by connecting the soldering-iron with a sourceof supply by means of a flexible tube which would not interfere with themanipulation of the soldering-iron by the workmen. I have indicated sucha connection with my improved soldering-iron in Fig. 3. In this form ofsoldering-iron the bolt is pro vided with any suitable burner andnipple, Z, to which a flexible tube, at, may be attached, and thenconnected to a source of gas-supply.

In the use of my soldering-iron it will be advantageous for the workmento have two or more irons, so that while one is in use the other may beheating over a gas-burner.

The handle (Z may be made of rod metal doubled upon itself to form thelimbs d d and the hand-grasp d the latter being made bulging, so as torender the limbs d cl springy. The limbs d (1 may diverge slightly fromthe upper end of the bow of handle d, so as to grasp the copper or boltmore firmly, the ends of said limbs next to the gudgeons g g lying inthe grooves e or f, in accordance with the position the bolt may beplaced in with respect to the handle. The roof of the gaschamber may bearched or flat, or any other approved shape.

YVhat I claim is 1. In a soldering-iron, a bolt or copper having aninternal gas-chamber provided with flame-outlets and air-inlets, and anexternal projection arranged above the flame-outlets, substantially asdescribed.

2. In a soldering-iron, a bolt or copper pro vided with an internalgas-chamber of spherical or nearly spherical shape, as set forth, andprovided with air-inlets and flame-outlets, and a handle, to which saidbolt is pivoted, substantially as described.

3. In a soldering-iron, a bolt or copper having an internal gas -chamberspherical or nearly spherical in shape, as set forth, provided withair-inlets and flameoutlets, and a shoulder arranged above the saidflame-outlets, substantially as described.

4. In a soldering-iron, a copper or bolt provided with sockets c andgrooves e and f, combined with a handle having gudgeons and spring-limbsengaging, respectively, the said sockets and grooves of the bolt,substantially as described.

5. The combination of a copper or bolt having an internal gas-chamberprovided with air-inlets and flame-outlets, and also having sockets cand grooves c andf, a gas-supplying device attached to said copper orbolt, and a handle secured in said sockets and engaging the said groovesas the copper or bolt is placed in position, substantially as described.

6. The copper or bolt having an internal gas-chamber provided withair-inlets and flame-outlets, and also having sockets c and longitudinaland transverse grooves, combined with the spring-handle engaging thesockets and grooves, substantially as set forth.

In testimony whereof I have hereunto set my hand this 30th day of June,A. D. 1887.
